Thank you very much for this video. I was able to pull my first alternator out of my 2003 Nissan Altima. I was able to cheat a little. I took out the top and bottom bolts because I couldn’t get the belt to slide off even pushing on the tensioner. The bottom bolt I had to finish with a 14 mm crescent wrench. I was able to pull up the fuse box just enough to get that bolt to slide out because I didn’t have the right tool to take out the fuse box bolt. Then I used the pry bar to push to the alternator out and as it dropped the tension in the belt released enough to pull the alternator out without having to remove the belt from the pulley. This video was extremely useful for a backyard mechanic like myself
Thank you! This video saved me $200 in labor. We did have to take out the coolant overflow and the entire fuse box to get that long bolt out but it was worth it!
Yep had to do this to. Not as hard as I thought it would be. Protip is you don't have to remove the last fuse box bracket bolt, you can just pivot it to get the bolt out of the way
After viewing this RUclips video my neighbor and I did my 2002 Nissan Altima today! It worked out beautiful!
Thank you for watching. Please let us know how the repair comes out!

For those saying you need to remove the fuse box and coolant container, you really dont have too. I also thought I was going
to need to do so, but if you pull the fuse box up enough, it gives clearance for the long bolt to come out. Then again I was being
a bit lazy to take another 5-10mins to remove everything lol. But great video as always!
+mario alvarado Thank you for your feedback!

Awesome. We're glad the video helped you two out. 1aauto.com 866-403-3393
That can't be true
Can't thank you enough!! Ordering the alternator shortly. 1A has saved my butt more than once!!!! Thanks to you I can do it myself.

Posting some feedback for others, as I just spend ~2 hours working on this.
First, the video is supper helpful. The tools needed are 100% correct, and the order of things to do is correct. However, if you have an older car, and depending on the model, here are the things I ran in to while taking on this task. -- 2003 Nissan Altima 2.5
1. Check the wires that feed in to the alternator. The tape and the plastic wrap that holds the wires for signs of damage because you want to fix that. ASAP. I re-wraped mine in high-temp tape they use for HVAC. The plastic and the electrical tape will only last so long.
2. In the video the presenter mentions that fuse box being in the way, when yes it is. In fact the bracket was completely in the way on my car, and the bolts were rusted to the bracket. After a lot of WD40 and patience I was able to get the bracket loose enough to wiggle it out of the way get the bottom bolt of the alternator out.
3. The space you are working in is super tight. Have on hand some pipe to use to as a breaker bar to break the bolts loose if needed, or you can use that trick with open ended wrenches and link them for leverage.
4. Consider some velcro or zip ties to secure the belt in a place where it won't move out of place and fall off the other pulleys. I lucked out because I had something in my box. If you don't, it could move out of place and now you need to get under the car to see the back of the block, or really skinny arms, flashlights, and mirrors on the floor to see what you are doing.
5. On my car, the break light and battery light came on (no check engine) when I had the battery checked at the auto parts store. When I replaced the alternator, all the red lights went away as the computer reset. Keep in mind, some lights could reappear later on, and you will need to have it checked out. The computer in the car will do weird things when the power is not consistent. Sort of like when HAL in 2001 a space odyssey.
Have fun folks!
+Phil Caswell Thanks for the input, always appreciated! 1aauto.com
I also had the brake and battery light to on in my dash. I have a 2010 Versa 1.8l. Thanks for the added info. Very helpful!
That’s how you know it’s not a battery problem, but an alternator problem. Just when my car was about to die, the ABS light also came on.
@@znhait that's exactly what mine is doing now (Brake and battery light come on. Usually they flicker. I've never seen them come on solid and stay on they flicker and my car loses acceleration then will catch and drive fine again. Now it died completely this initially happened about a month ago and I had my battery, alternator and starter tested. The battery was bad I replaced it and the terminals. Since its flickering and the engine basically does the same could it also be an electrical issue? Wiring to the alternator? When it flickers the electronics (display lights, headlights, radio, etc) still work. When I see the brake and battery light display a solid bright red its pretty much instant that the car completely shuts down.
Cheapest part and easiest instructions possible! Replaced mine in my 2005 Nissan Altima. Probably saved well over 100 dollars. Thank you so much for these videos!

+PiffSett Thank you! We love empowering our customers and showing how to perform DIY auto repairs with our high-quality auto parts. 1AAuto.com
thanks for this video today I was able to change the alternator of my sister's car following all the steps, keep making videos like this for those of us who know nothing about mechanics.
Currently watching because I'm about to help my mom do hers.
if you have a 2005 you will have to remove the two bolts holding fuse compartment as there wont be enough clearance when backing the lower 14mm bolt out because it will hit the metal frame holding the fuse box...just did it today...
I didn’t go to the comments until about 30 minutes of wanting to break everything, thank you!!!
Duley noted. Thanks
Just ran into that issue as we speak
Yep, and when you put the bolt back in, I recommend using an extension on your rachet and using that extra space to clear the alternator pulley allowing you to have a lot longer strokes of your ratchet
Just used this video to get my car back on the road tonight. Saved me a tow bill, repair bill and my wife’s nerves. Thanks!

What was the 5mm bit Allen used for?
replaced the alternator in my '02 sentra se-r 2.5l after watching this video. ive never done more than changing a tire but i had the new alternator secured in under an hour. thanks much :)
Thank you for watching. Please let us know how the repair comes out!
1aauto.com 888-844-3393
Thank you I changed my 1st alternator God bless you
Great vid. After forgetting a wire, my car wouldn't start and gave p1760. Attached the missing wire, cleared the code. All seems well. This fixed my problem with the belt vibrating loudly every so often.
Video was very helpful especially when it came time to move the tension idler. I thought I was going to have to loosen it and then readjust...very helpful!
I would recommend removing the coolant overflow container (2 bolts), then lift the fuse compartment and finally remove the 2 bolts holding the fuse compartment bracket. This takes only 3-4 minutes and gives tons of clearance for the long bolt and easier access to the tension idler. No burns or busted knuckles this way ;-)
awesome tip Paul....I can swim in that space now hahaha!!!
Super helpful, man. Auto guy was gonna charge me $450. I'll check out A1 when I need parts going forward.
Hey! Thank you so much! Really saved my bacon! I had the new alternator on, and the main bolt in place, but the belt was too tight for me to get the thing in place for the second bolt! I was freaking out. The first video I watched about adjusting the tension did not apply to my car. Following your instructions turned out to be super easy! I thought I was going to have to loosen and then re-tighten something, but I just levered that wheel down and moved the alternator into place! God bless!
found best price for new alternator from 1A Auto, and followed video exactly as shown, finished in about an hour. Tested with multimeter at battery, and it charges great! Thanks 1A Auto!!!

No Problem!
Thanks for the help! That bottom bolt was a bear but other than that, everything went smooth with your awesome walkthrough.
Thanks for watching. 1aauto.com 888-844-3393
yes im havin prblems putting bottom bolt back in.. no room. the guy in the video made it look too easy
Thank you guys you helped me figure out how to take out the belt I was struggling with it just changed my alternator today on my 05 :D
Ah, this unfortunately did not solve my problem, but this was a great walkthrough on how to remove & swap an alternator. Thank you!
It's already been said but here is one more Great demonstration!!! You made what I thought was going to be difficult very easy Thank you
+Dogs Ear That's our goal. We're glad we could help you out. 1aauto.com 866-403-3393
video is definitely helpful however I now have a new enemy a serpentine belt that was the hardest thing to put on thank you for the video it saved me a lot of money and time
One of the best concise videos, well done
+John Tancsics Thanks for the feedback!
This worked pretty well for my 2005 SL. But I had to remove the coolant overflow tank and the mounting bracket for the relay box, because the bottom bolt wouldn't clear the relay box mount. It was a bit of a pain, but gave me lots more room, too. Not sure what was different about mine, but there was no way that it was coming out without moving that bracket. Other than that, great instructions! Thanks.
Thanks for the video! I just did my 2004 Altima. The only modification is that I had to unscrew the fuse box mounting bracket to get enough clearance to get the bolt out. I didn't have to remove the whole thing, just slide it over a little.
how did u get the fusebox to slide up a little? cant seem to get this one to slide up enough to put bolt back in. had to walk away and try another time. workin on a 03 altima
Thank you very much for your videos❤🎉
Very helpful! only on a 2003 Sentra SER spec V the tensioner bolt is down a bit farther and the belt was a little tricky to get back on by myself, Had a friend help hold the back part while i released the pressure on the bolt. Other than that great guide!
You guys got the best vids! Thanks
Thanks for watching. We're glad you liked it. 1aauto.com 866-403-3393
Is it the same process for the v6
Thanks for your video that it helped me to fix my car by my self.
A huge help. Thank you!
+T G Thank you for your feedback! We are happy we could help.
You guys need to make a video for doing this on the 3.5 V6 models, because it's more involved (have to remove the radiator). Not impossible though..
This was a great video! My son watched this video in order to learn how to give the belt slack via the belt tensioner. Thank you!
awesome video thank you
Excelent video, ty master from Guadalajara Mexico
+Jair W4 Thanks for checking us out! 1AAuto.com

This was a great video. Thank you very much
Does the engine cover need to go back on or can it be left off?
thumbs up for 1A auto ..
I tried replacing my alternator but the second screw the one on the side you said to loosen it up so I could pull the screw out didn’t work. I had to remove the screws from the bottom and removed the whole bracket instead of just screw on the side fuses box. Thanks you for the video you posted on RUclips.
Thanks for your comments and for checking us out. 1aauto.com +1jonrd
do the same steps apply for a 2002 2.5 s
Great help guys. Thanks a lot for your videos.
I would like to mention that on my 2006 Altima , I also had to remove the fuse box bracket in order to get that lower alternator bolt out. FYI !!
How do you make the ratchet go so fast? LOL Nice video
Thank you for watching! Trick photography. Glad to be of help. Let us know how the repair turns out. 1aauto.com 888-844-3393
What was the 5mm bit allen used for? I keep missing it in the video. Thanks!
+Cookiezandope It is used to remove the engine cover bolts. Check out the video at the 1:00 mark. 1aauto.com
Thank you for this video. it was very helpful.
Video was very helpful
Thanks for checking us out. 1aauto.com +Eugene Haley Haley
Nice edit too. Sweet video
Thanks for checking us out. 1aauto.com +Daddys Baby
At least the Nissan engineers were smart enough to mount the alternator front and topside for easy access. The stupid Kia engineers mounted it rear and bottom, making it very difficult to remove and replace. It picks up a lot of dust and road grime and fails prematurely.
are the alternators from 2002 to 2006 the same?
Great video tutorial.
+Rogelio Beltran Thanks for checking us out! 1AAuto.com
Can the serpentine belt be replaced at this time from the top of the engine bay?
Thanks
Thanks, y'all saved me ( again) haha
i stuck in the higway with bad alternator right now with the same.2003 altima car
Good job! I like a FF video trick -- thanks you!!
That same car and that same job will take a lot longer if you have the V6 trim
Very helpful video ..Ty
How do u take off the little clip that holds the wire from the alternator to the sensor on the a/c clutch without breaking it?
Never use a pry bar to remove a bolt. Instead move the fuse block out of the way it just lifts up once the tabs are released. The bracket is actually what blocks the bolt removal. So loosen one bolt and remove the other. Now you can pivot the bracket out of the way and the bolt is easily removed. This way you won't damage the threads of the bolt with a pry bar or bend the bracket making installing the fuse block difficult.
+Ronin Mantis Thanks for the feedback!
I snapped the lower bolt on the alternator. What's the correct size for a replacement? Thanks!
+MrSourkeys Thank you for your inquiry but we do not have the spec on that bolt available. 1aauto.com
Can u plz make a video changing the belt much appreciated
HI Luis, We'll keep this request in mind in the event that we need to make this repair in the future. Have a great day! 1aauto.com 888-844-3393
my alternator is way gone. I will be replacing it soon. Hopefully this will save me around $300 in labor.
+ChilangoGONEWILD Thank you for watching. Please let us know how the repair comes out! 1aauto.com 888-844-3393
I want to know if I can use the same alternator for Nissan Altima and Murano
+Michael Haywood These vehicles use different alternators.
Torque spec for 14mm bolts?
Easier to put top bolt in few threads then dangle bottom until bolt slips in. Much easier
Can’t seem to get the 14mm screws loose at all !
Is this the same for 2009 Altima? I'm hoping it's easy for me to replace for a female.
+Stacie James This procedure might be different for your application. We do not currently have a how-to video for this particular year, make and model. Thank you for asking! 1AAuto.com
Don't forget to take ur battery off or u could risk shorting out something
ohhh and thank you very helpfull
how long should the 14mm wrench be estimated?
Though is the the same procedure for a 2006 Sentra? Everything's pretty much going to look the same?
It may be a similar procedure. Thanks for watching.
Thanks for answering :-).
I'll post my experience for others...
The Sentra (1.8 L), while similar, had some differences. I think it uses a completely different belt system. I ended up taking the bearing off, but I think there is probably an easier way.
Also, there are 3 bolts, not 2. And one of the bolts was incredibly difficult to get out. I'd recommend hitting each of the bolts with a lubricant and giving it some time, because one of them I had to give it overnight, and then was able to get out in the morning.
Also, the third one comes out directly into the heat shield, and I couldn't get it out easily. The only ratchet I had that would fit was about 6 inches long. And I had a breaker bar, but there just wasn't enough room to get it in, even after taking off the heat shield. In the end, I just sprayed it with some lubricant and went to bed, and it came out in the morning. I think a wrench that could angle at like 45 degrees, and perhaps a cheater bar would be useful,as it's rather difficult to get in there. Or maybe accessing from the bottom, but there isn't much space.
Finally, the Sentra is a subcompact. There just isn't much space. I had to remove a couple other bolts just to get it out.
So in the end, it probably only took me about 6 hours to do a job that would probably take a mechanic 30-60 minutes to do.
The bottom alternator bolt is just spinning when I try to take It out. how can I make it stop spinning, that's the only thing holding me back from removing the alternator
Why won’t the bottom bolt come out? Not even with my impact is loosing it
Thanks man
Thanks for watching. Have a great day! 1aauto.com 888-844-3393
Antbodys car turn on but not run when they stepped on the gas?? My car switches from P to D im hoping its the Alternator because it was making a weird noise
Thank you.
Help. I have replaced my alternator and battery but my battery keeps dyeing
Does your new alternator come with new nuts and bolts??? Just in case????
+Chris Romero Thanks for watching! Our new alternator does not come with new hardware, so you will either have to reuse the originals or get new ones. Here is a link to the alternator if you or any other view would like to make this purchase: www.1aauto.com/1A/alternator/Nissan/Altima/1AEAL00411?RUclips&CTA+Comment&U8o
It's a bit more difficult to do in the sentra, spaces are tighter.
Hi there does it work on nissan presage 2.5 2004?
+EDMOND SERRANO It may be a different procedure on your application. We currently do not have an auto repair video for this particular year, make and model. Thank you for asking. 1aauto.com
I followed fuse box on 2006 the metal part I had to put 🔨 down.😅
Will this be the same on 3.5 v6
+Jordan Valdez We currently do not have an auto repair video on this particular repair. It may be a different procedure that what's shown in this video. We do carry a brand new alternator for that application. Here's a link to them on our website if you would like to take a look at them. There's no core charge on these and they are 100% new they are not rebuilt. www.1aauto.com/2002-06-nissan-altima-alternator/i/1aeal00443?f=663161&y=2006&RUclips&CTA%20Mirrors&ATony
This process is NOT the same for all models 2002-2006. My 02’ Altima SE requires you to pull off the passenger tire and go in from underneath. MUCH more of a pain.
Is a2012 the same.??? Nissan Altima???
+Chris Romero It would be a very similar process for the installation.
will this be the same for 2013?
+Kelevra Verde Probably not, no. 1aauto.com?RUclips&CTA%20Comment&ATony 866-403-3393
I just did this and when I went to put the negative terminal back it sparked and a fused popped on the positive terminal?!?!
Now my car doesn't start
02 Nissan Altima alt. not like this. It sit to low with ac holes over it and cooling holes over it check my.y channel out as we fix this 2002 Nissan Altima se 3.5l..
hex bolts won't come out of engine cover. one of them is starting to strip what the hell do I do ?
i figgured it out never mind. thanks for the video!
Mine is an 03 3.5 and the alternator is not in the same place.
+Aaron Terry Yes, the vehicle in the video has the 2.5L engine as stated at the beginning of the video. We do not have a video for this repair right now, but we'll keep this request in mind for a future video! 1AAuto.com
What are the torque specs?
+Richardson Rodolfo Thanks for checking us out. We do not have these specifications at the moment. You can refer to your owners manual or a forum to see if you can get the torque specs for these various parts there.
